STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 595,138, dated December'7, 1897.

Application filed February 20, 1897. Serial No. 624,480. (No model.)

To all whom t may concern:

Be it known that we, ADOLPH BLACK and LUTHER E. GREGORY, citizens of theUnited States, residing at New York, in the county and State of NewYork, have invented new and useful Improvements in Station-Indicators,of which the following is a specification.

By means of this invention streets or stations-snch as those beingapproached, for example, by a car or conveyance-can be indicatedautomatically or have their designations exposed to view of passengers;and the invention relates to novel arrangements by which practicallyuniform and accurate actuation of the indicating-strip can be secured,as also to other features set forth in the followingspecificationandclaims and illustrated in the annexed drawings, in which- Figure l is asectional side elevation of a station-indicator. Fig. 2 is a sectionalfront elevation of Fig. l. Fig. 3 is a detail side view of a reversinggear or train in different position than in Fig. l. Fig. 4 is a planview of Fig. 3. Fig. 5 shows a driving mechanism for the worm-shaft.

A casing or box U, adapted to be secured at a suitable place, as insidea railroad-car, has a sight or openingV .for exposing to view therequired station or information on the traveling strip K. Into this boxU extends a rotary worm-shaft O, actuated by suitable gearing orconnection, as with a car-wheel or auxiliary wheel. This worm-shaft Crotates gear E on shaft D, and gear F is connected to or rotates withgear E.

On shaft D swings the arm R of a reversing gear or mechanism, said arm Rcarrying a rotary gear G, meshing with gear F. To arm R is jointed alink l, jointed to a link 2, having a pivot or support 3 on a side orsuit able part of the case U. The links l and 2 form what may be calleda toggle-joint. At the joint of links l and 2 is mounted the rotary gearII, meshing with gear G. The arm R projects through a slot or opening Yin the case, and by swinging arm R to the position shown in Fig. l gearHis made to mesh with gear I to rotate the latter in one direction. Thegear G is now out of mesh with gear I. YVhen the arm R is moved to theposition shown in Fig. 3, the wheel H is moved out of mesh with gear Iand the gear G is moved into mesh with gear I, so that the latter isrotated in the opposite direction, gear H now running idle. By movingarm R to a position intermediate between that shown in Figs. l and 3, sothat both gears G and H are out of mesh with gear I, the latter is leftto stand still.

The gear I is fixed to shaft A, to which is fixed a driving-drum J, andgear I meshes with gear L, fixed to shaft 5, to which is fixed asmoothing-drum O. The drums J O, rotating at equal circumferentialspeeds, feed the strip K in one direction or another.

The driving-gear I meshes into gear M, which in its turn meshes withgear N, so that gears M and N rotate in opposite directions. These gearsM and N are mounted loosely on shafts t3 and 7, and each gear has fixedthereto an eccentric stud 8 and 9, to each of which is fixed an end of acoiled spring, as 10 and ll, respectively, having their other ends fixedto shafts 6 and 7. To these shafts 6 and 7 are fixed the drums P and Q,on one of which the strip K is wound while unwinding from the other, andvice versa.

The springs 10 and 1l, it is noticed, coil about the shafts 6 and 7 inthe same direction, while the gears M and N rotate in oppositedirections. The strip K passes over guide-roller T in traveling to orfrom drum P.

To make the strip travel in the direction of arrow l2, Fig. l, the drumP, with gear N, r0- tates in the direction of arrow 13, and the drum Q,with gear M, rotates in the direction of arrow 14. This rotation of gearN tends to cause an unwinding or slackening of the spring ll, so as toease the delivery of ribbon K from the drum P, while the rotation ofgear M tends to wind up or tighten spring lO to cause an efficienttake-up of ribbon K by drum Q.

When gears G and H are out of mesh with gear I, the drum J, with stripK, can be set or adjusted by crank or handle S, Fig. 2.

The drum or rollers P and Q may be considered carrying-rollers, sincethey carry or support the strip or ribbon K in readiness to be deliveredto or taken from roller or driving-drum J.

J ointed to reversing-arm R at 16, Figs. l

and 3, is an arm 17, the free end of which is forked to straddle shaft5, as seen in Fig. 3. Said free or forked end is cam-shaped, having itscentral part 18 high or wide, as seen in Fig. 4, and narrowing to theend portions 19. These cam portions 18 19 as the arms R and 17 areshifted move back and forth in the groove or way 2O of the friction-disk21, sitting loosely on shaft 5, but prevented from turning-as, forexample, by the engagement of cam part 18 into said groove 20. When thearm R is shifted to one extremity oranother of its throw, one or anotherof the low cam parts 19 is between the disk 2l and the collar 22,sitting loosely on shaft 5 and eX- posed to the action or pressure ofspring 23. Vhen, however, the arm R is in intermediate position to holdboth the gears G and-H out of mesh with gear l, the high part 18 of thecam 18 19 is moved between the col1ar 22 and the disk or brake 21, so asto press the latter against gear L and prevent the latter, with drum Oand strip K, as also drum J, from moving. The strip K is also thusguarded against accidental displacement or shifting.

The pin or fulcrum 24 supports a handle or lever 25, sufficiently looseor free to allow this leverv to be moved for taking or moving thespring-pressed collar 22 away from cam part 18 when said cam, with armR, is in middle or intermediate position, if the gear L is at such timeto be temporarily freed, as when setting by the handle or crank S. Thehandle 25 projects out through a slot or opening 26 in case U, so as tobe conveniently reached.

The shaft 4 is shown supporting swinging arms 27 concentrically with thedriving-drum, Figs. 2 and 3, said arms carrying spring-boxes for theshaft 5 of drum O, so. that the latterV is held in proper contact withthe drum J or strip K.

The shaft C is shown actuating a gear 28, Fig. 1, having an eccentric orcrank pin 29, reciprocating link 30, jointed to arm 31, swinging onshaft 32. This arm 31 carries a paWl 33, engaging ratchet 34 to rotatethe latter with shaft 32. This shaft 32 being given a step-by-step orgradual rotation is made to successively expose leaves or advertisingfaces 35 through sight V". The ratchet 34 can be secured againstretrograde motion by a stop-pawl 36, or said stop-pawl may form or bepart of a hammer or sounding device for announcing an actuation of theadvertising device.

The gears F and I may be considered actuating or driving gears, havingthe interposed pair of connecting-gears G and H.

By having the slot 2O deepened toward the periphery of disk 21, the campart 18 enters such deepened slot part when said cam-is in releasingposition and enablesl the disk or brake to move from gear L to free thelatter,

While, when in central position and pressing on the high or central partof slot 20, the cam 18 holds the brake 2l in action, or in place of theslot 2O being curved the face of collar 22,

shifted. ample, run around a loop to shift to the return-track, thereversing-gear will have to be shifted by lever R.

vice or leaves will always be moved forward.

If the car at the end of the trip is not turned around, so that on thereturn trip the end of Athe car which before was the rear end now for-msthe front end, the arm R need not be lf, however, the car should, foreX- What we claim as new, and desire to secure by Letters Patent', is-
